The original TV cop show has been so updated here, it barely registers as the same product. But for all the steely modern cityscapes and pulsating action, this a 21st century cop thriller with 1970s values, both in terms of its shouty, louty, rule-bending lawmen (Winstone is a parody of himself) and its "hand in your badge" cop-movie cliches. And as for political correctness – leave it aaaaht!
